Dracos
this reptilian humanoid was part of the first group of students Luke Skywalker ever trained, during the period immediately following the Battle of Endor. Dracos admitted that he was frustrated at the lack of training in the use of the Force, and he openly questioned Luke's failure to focus on that aspect of training. Luke explained that the ability to touch the Force was vastly different than being able to actually use it, and that he lacked the ability to gauge an individual's connection to the Force. Luke was also worried that he might, inadvertently, create another Darth Vader.
